Abstract

In a connector for electrical connection between relatively rotatable parts such as a steering wheel and column of a vehicle, the connector has a housing with a stator (1) mountable on the column and a rotor (3) on the steering wheel and the stator (1) and/or the rotor (3) of the housing being wholly or partially provided with a coating (9, 10) of noise damping material e.g. polyester or polyether. The housing defines an annular chamber (5) which surrounds the rotor and serves to accommodate a conductor strip (6) that loops around the rotor in a plurality of windings. The rotor (3) and the stator (1) each have openings along the three radial lines, the coating being sprayed through the openings in such a manner that radial ribs (11, 12) are formed on the side forming the interior of the housing, and the conductor strip (6) detachably abuts against said ribs with its lower and upper edges respectively. <IMAGE>

Description

Die Erfindung geht aus von einem Stromleitungsverbinder gemäß dem Oberbegriff des Patentanspruches 1.The invention relates to a power line connector according to the Preamble of claim 1.

Ein Stromleitungsverbinder dieser Art ist beispielsweise aus der US 4 722 690 bekannt geworden. Sie werden insbesondere zur Herstel­ lung einer elektrischen Verbindung zwischen einer Stromquelle und der in der Lenkradschüssel angeordneten Gassack-Aufprall-Schutzeinrichtung von Kraftfahrzeugen, darüberhinaus jedoch zur Verbindung der im Lenkrad angeordneten Schalter für beliebige andere Funktionen mit einer Stromquelle verwendet. Hierbei weist das im Gehäuseraum angeordnete Leiterband eine solche Länge auf, daß sie dem beidseitig etwa drei Umdrehungen betragenden Lenkradausschlag zu folgen vermag, wobei sich die Feder während des Lenkradausschlages aus einer mittleren Lage in der einen Richtung bis zur Anlage an dem stationären Gehäuse nach außen aufweitet und in der anderen Richtung bis zur Anlage an dem Rotor nach innen zusammenzieht.A power line connector of this type is, for example, from the US 4,722,690. In particular, they become a manufacturer an electrical connection between a power source and the Airbag impact protection device arranged in the steering wheel bowl of motor vehicles, but also for connecting the steering wheel arranged switch for any other functions with a Power source used. Here, that arranged in the housing space Conductor tape of such a length that it has about three on both sides Steering wheel deflection can follow revolutions, whereby the spring during the steering wheel deflection from a middle position one direction to the outside of the stationary housing expands and in the other direction until it touches the rotor contracts inside.

Die bekannten Stromleitungsverbinder haben sich in der Praxis im wesentlichen gut bewährt, es wird jedoch als ein Nachteil angesehen, daß das in dem Gehäuse geführte Leiterband einerseits bei der, normalen Lenkradbewegung Kratzgeräusche und andererseits bei plötzlichen starken Erschütterungen - etwa in Kurven oder bei Fahren auf unebenem Gelände - starke Klappergeräusche abgeben, die vorwiegend durch das Aufeinander­ schlagen der Windungen des Leiterbandes aneinander verursacht werden.The known power line connectors have in practice well proven, but is considered a disadvantage that the conductor strip guided in the housing on the one hand in the normal Steering wheel movement scratching noises and on the other hand when suddenly strong  Shocks - such as in curves or when driving on uneven terrain - emit strong rattling noises, mainly due to the collision beating of the turns of the conductor tape against each other are caused.

Zur Vermeidung dieses Nachteils ist aus der EP 04 17 350 A1 ein Stromleitungsverbinder dieser Art bekannt geworden, bei dem im Stator des Gehäuses in radialer Lage mehrere Federplättchen angeordnet sind, mit deren Hilfe das Leiterband bzw. seine Windungen lose gegen den Ro­ tor gehalten werden. Am Umfang des Gehäuses sind radial gegenüber­ liegend gleichsinnig zwei nach innen gebogene Federzungen angeordnet, die sich auf der äußeren Windung des Leiterbandes abstützen. Die Ein­ bringung der Federplättchen erfordert einen zusätzlichen Herstellungs- und Montageaufwand.To avoid this disadvantage, EP 04 17 350 A1 Power line connector of this type become known in the stator several spring plates are arranged in the radial position of the housing, with the help of the conductor tape or its turns loosely against the Ro be held. The circumference of the housing is radially opposite lying in the same direction, two inwardly curved spring tongues arranged, which are supported on the outer turn of the conductor tape. The one bringing the spring plate requires an additional manufacturing and assembly effort.

Der vorliegenden Erfindung liegt als Aufgabe die Schaffung eines Stromleitungsverbinders zugrunde, mit dessen Hilfe auf eine einfache Weise die Geräuschentwicklung verhindert werden kann. Diese Aufgabe wird mit einem Stromleitungsverbinder mit den im Patentanspruch 1 wie­ dergegebenen Merkmalen gelöst.The present invention has for its object to provide a Power line connector based, with the help of a simple Way the noise can be prevented. This task is with a power line connector with the in claim 1 as the given features solved.

Der erfindungsgemäße, aufgrund der weichplastischen Beschichtung ausgezeichnet gedämpfte Stromleitungsverbinder ist einfach herstellbar insofern, als die Dämpfung in der der Herstellung der Teile dienenden Form, d. h. unmittelbar im Zusammenhang mit der Herstellung der Teile selbst aufgebracht werden kann. Die gesonderte Anfertigung von Dämpfungselementen und deren Montage in einem weiteren Arbeitsgang ist nicht erforderlich.The inventive, due to the soft plastic coating excellently damped power line connector is easy to manufacture insofar as the damping in the manufacturing of the parts Shape, d. H. directly related to the manufacture of the parts itself can be applied. The separate production  of damping elements and their assembly in a further operation not necessary.

Der in der Zeichnung wiedergegebene Stromleitungsverbinder zur Überbrückung von Leiterunterbrechungen zwischen einer fahrzeugfesten Lenksäule und einem auf der Lenksäule drehbaren Lenkrad besteht aus dem an der Lenksäule befestigbaren Stator 1 mit Leiterabgang 2 sowie dem mit dem Lenkrad drehbaren Rotor 3, der ebenfalls mit einem Leiterabgang 4 versehen ist. Stator 1 und Rotor 3 bilden ein einen Ringraum 5 umschließendes Gehäuse, das der Aufnahme eines den Rotor in mehreren Windungen umschlingenden, in den Leiterabgängen 2, 4 endenden Leiter­ bandes 6 dient. Hierbei können die Leiterabgänge von einem Kontaktstift gebildet sein, an dem die Enden der Leiterfeder befestigt sind, es kann jedoch auch das Leiterband 6 selbst - etwa durch Umspritzen - durch den Rotor bzw. die Statorwandung geführt sein, so daß das Leiterband selbst die Leiterabgänge bildet. Es ist weiterhin der Stator an seiner Innenseite mit einem Ringflansch 7 versehen, die als Führungsfläche für den sie mit einer Ringschulter 8 umgreifenden Rotor dient. Fig. 4 is a section B-B through FIG. 2
The power line connector shown in the drawing for bridging conductor interruptions between a steering column fixed to the vehicle and a steering wheel which can be rotated on the steering column consists of the stator 1 with a conductor outlet 2 which can be fastened to the steering column and the rotor 3 which can be rotated with the steering wheel and which is also provided with a conductor outlet 4 . Stator 1 and rotor 3 form a housing 5 which encloses an annular space and serves to accommodate a conductor band 6 which wraps around the rotor in several turns and ends in the conductor outlets 2 , 4 . Here, the conductor outlets can be formed by a contact pin to which the ends of the conductor spring are fastened, but the conductor strip 6 itself can also be guided through the rotor or the stator wall, for example by extrusion coating, so that the conductor strip itself forms the conductor outlets . Furthermore, the stator is provided on its inside with an annular flange 7 , which serves as a guide surface for the rotor encompassing it with an annular shoulder 8 .

Bei dem in der Zeichnung wiedergegebenen Stromleitungsverbinder sind Stator und Rotor teilweise mit einer Beschichtung 9, 10 aus weich­ plastischem Material versehen derart, daß sie jeweils entlang dreier radialer Linien Durchbrechungen aufweisen und die Beschichtung derart durch die Durchbrechungen durchgespritzt sind, daß auf der den Gehäuse­ innenraum bildenden Seite radiale Rippen 11, 12 gebildet sind, an denen sich das Leiterband mit seinen unteren bzw. oberen Kanten anlegt. Hier­ bei ist die Beschichtung des Stators auf der Außenseite um den Ring­ flansch 7 geführt, wodurch eine Dämpfung nicht nur der Führungsflächen für das Leiterband sondern darüberhinaus auch eine Dämpfung der Füh­ rungsflächen zwischen Rotor und Stator erreicht wird.In the power line connector shown in the drawing, the stator and rotor are partially provided with a coating 9 , 10 made of soft plastic material such that they each have openings along three radial lines and the coating is sprayed through the openings in such a way that the interior of the housing forming radial ribs 11 , 12 are formed, on which the conductor strip bears with its lower and upper edges. Here, the coating of the stator is guided on the outside around the ring flange 7 , whereby damping not only the guide surfaces for the conductor strip but also a damping of the guide surfaces between the rotor and stator is achieved.
